Due to electric part box main part 31 turned upside down, therefore cable bullport 310 moves to top ceiling side.
The cable 80 being directed to cable bottom surface depression part 512 crosses cable bottom surface depression part 512, move along cable side-facing depressions part 501,511, and the outside of main unit 150 it is drawn to from the top of the first cable extraction groove 604, then it is directed in electric part box 3 from the cable bullport 310 of electric part box main part 31.
According to this installation method, such as, even if when electric part box 3 is moved to another position from a position by the installation position according to refrigerant distribution unit 15, it is also possible to the convenient ground mobile electrical parts case 3 when keeping cable 80 to connect.
Next, cable draws the first cable that groove lid 64 is installed in the part being formed in and not installing electric part box 3 on upper housing 60 draw groove 604 and the 2nd cable and draw in any one in groove 605. Draw groove lid 64 due to cable and be formed as longer than cable extraction groove 604, and due to the symmetrical position that cable extraction groove cap bore 606 is formed on first wall 60c and the 2nd wall 60d, therefore cable can be drawn groove lid 64 and it is installed in any one in these surface portion. The upper pawl that cable is drawn groove lid 64 is fixed in cable extraction groove cap bore 606, then, utilizes screw to make cable draw groove lid 64 and engages with upper housing 60. Cable can be drawn groove cap bore 606 and be hidden from outside by this structure. , it is possible to improve the outward appearance of upper housing, therefore and be possible to prevent dust invade upper housing inside.
